Specification of Letters Patent.

Elatented Aug. 8. 191.6.

Application filed Jane 21, 1915. Serial'No. 35,441.

. To all whom it may concern Be it known that T. "ALTER L. Knox, a citizen of the United States, residing at La Fayette, in the county of Tippecanoe and State of Indiana, have invented certain new and useful Improvements in Protectors for Automobile-Radiators, of which the following is a specification.

The object of this invention is to provide a protector or hood to prevent the radiation of heat from the radiators of automobiles. the object being to protect the radiator against the freezing of the liquid contained therein while the automobile is standing idle in freezing weather.

Another object of the invent-ion is to provide a protector that can be easily put in position on the radiator and removed therefrom, and which does not interfere with any of the parts or fastenings of the hood.

Another object of the invention is to provide an improved fastening device therefor to hold the protector in place.

These and other objects of the invention will be fully illustrated in the drawings. de

scribed in the specification and pointed out in the claims at the end thereof.

In the drawings, Figure 1 is a perspective *iew of the bonnet and radiator of an automobile showing the protector in place. Fig. 2 is a vertical section through the protector, the section being taken on the line Q -Q of Fig. 1. Fig. 3' is a horizontal section through the protector, the section being taken on the line 3 3* of Fig. 2. Fig. i

' is a horizontal section through the protector, the section being taken on the line et J of Fig. 2.

- is formed of a single sheet bent double with the lower edge formed as shown in section formed of a single piece at the top of Fig. 2, the front edge being turned in on itself at the bottom and the rear edge being bent rcarwardly, and down to form a groove between the two plates to receive the top of the sliding shutter 11 when it is at the top of the protector. 'At the sides the inner edge of the flange is bent in as shown at (3 in Fig. 3. Inter-locked with this inner edge of the flange is one edge of a Z-shaped plate 7. Along the rear side of the Z-shaped plate 7 is placed a flat plate or strip 8 which projects centrally of the radiator and with the outer edge of which the' Z-shaped plate 7 and the inturned flange 6 forms a groove in which the movable shutter of the radiator is held strip 8 and the Z-shaped plate 7 are fastened each to the flange 5 by means of bolts 9. A filler 10 preferably of wood is used to fill the open space between the Z-shaped plate and the shell and flange of the radiator.

In the guides thus formed on both sides of the radiator is mounted to slide a shutter 11 which shutter is formed of-two parallel metal plates with a sheet asbestos filler 12 between them. The forward metal plate is turned over the rear plate at both the top and the bottom as shown in section in Fig.

"2. To the front of the shutter is fastened a handle 13 by which the shutter may be raised and lowered.

Across the bottom of the protector is placed a pad 16 which is stationary. This pad is formed of two sheets of metal with an asbestos filler between them. The lower edge of the rear sheet is turned forward as shown at 17. The upper edge of the front sheet is turned down over the rear sheet. The ower edge of the front sheet is turned forward and then down and back. as shown at 18.engaging with the forwardly turned edge of the rear sheet. In this way the sheets are held together at the top and bottom with the "asbestos filler'between themand a flange is formed at the bottom of the pad which serves as a stop for the sliding shutter.. The back sheet of the pad is bent up re ersely along the sides and with the front sheetform side flanges for the pad which overlap the Z shaped plate 7 and by'which the pad fastened in place. Bolts 9 are used to clamp the parts together.

the strips 8 end at the top ofthe'pad, the pad forming the lower part of the guide for the shutter.

l The shell 4 is provided at the top with an opening toencircle the nozzle of the radiator which water is poured into the cap is first removed from the nozzle and the The cap is then screwed on in place holding the protector in position. If instead of a cap to close this openlng its re moval will ordinarily not be'necessary, The inside of the shell of the protector is lined at with felt or other suitable insulating material." To the shell are attached lugs 21 and 22 to which in turn may be fastened thongs or ropes, the free ends of which may be tiedto the lamp brackets of the nfachin e. This makes it easy to put the radiator protector in place and fastenit or remove it.
